Question

What are the factors that affect stability of a complex?

Answer 1

Stable objects are very difficult to topple over, while unstable objects topple over very easily. The stability of an object is affected by two factors: the width of the base of the object. the height of its centre of mass.

Answer 2

Factors affecting the stability of a chemical complex are as follows.

• The nature of the central metal ions is an important factor that maintains stability of the complex. Higher the oxidation state of the ion, nore stable is the complex.
• The nature of the attacking groups is important as more basic the attacking groups, it can easily donate electrons to the central atom and make the complex more stable.
• Chelating agents play an important role. Multi-chelating agents can bind to the central metal through multiple bonds and increase stability of the complex.
• Resonance in chemical complexes stabilize the species. For example, acetonylacetonate stabilizes the complex by resonance.
